I have what I assume to be BBA in my 150. It grows in small tufts only on glass surfaces - walls of tank, jagr heater etc. It is crazy hard to remove! Right now I'm just using an algae pad and elbow grease - does anybody have any better tactics to remove this. Any type of algae scrubber on a long handle won't work, you cant press down hard enough to remove the algae w/o breaking the handle.
